Adjustable socket system

An adjustable socket system comprising:

• a base;
• at least two longitudinal supports including a first support and a second support, each of the first and second supports having a distal end secured to the base and extending along a longitudinal axis of the adjustable socket system;
• and
• at least two shell components operatively connected to the at least two supports extending longitudinally and collectively form a socket wall defining a receiving volume adapted to receive a residual limb, the at least two shell components extending from the base, the adjustable socket system movable between an open configuration in which at least one of the at least two shell components is moved radially outward relative to the longitudinal axis to loosen a fit of the adjustable socket system, and a closed configuration in which at least one of the at least two shell components is moved radially inward relative to the open configuration to secure the fit of the adjustable socket system on the residual limb;
• wherein the at least two shell components comprise a first shell component wrapping around a lateral aspect of the residual limb and having a distal part attached to the first support and a proximal part slidably connected to the distal part such that the distal and proximal parts are longitudinally displaceable with respect to one another to adjust a length of the first shell component between a first length and a second length different than the first length;
• wherein the first support is arranged to correspond to a medial aspect of the residual limb, and the second support is arranged to correspond to a lateral aspect of the residual limb, the first and second supports being located opposite to one another relative to and across from the longitudinal axis with the base extending between and upwardly toward the first and second supports;
• wherein each of the first and second supports has an elongate configuration with the second support extending farther from the base than the first support;
• further comprising a tightening system arranged to move the at least two shell components between the open and closed configurations, the tightening system including at least one tensioning element operatively connected to a tensioning unit and slidably routed through a plurality of guides located on the first and second shell components, the plurality of guides are defined along or near a leading edge of one of the first and second shell components and each defining a curved pathway redirecting the at least one tensioning element such that the at least one tensioning element forms a loop between the first support and second shell component, or the second support and the first shell component.
